Toss in most of the feta, most of the chickpeas and arugula, if using. Season with salt to taste and transfer to a serving platter. Top with bagel chips and remaining feta and chickpeas.

Use your air-fryer to whip up a healthy and delicious snack or light lunch of pitta chips with crispy chickpeas and hummus. They are also great as nibbles if you have friends coming round.
